I've searched and searched on Google, and I can't find anything that even seems applicable to my situation, let alone solves the problem. It doesn't matter which address in my website I try to navigate to (even addresses that don't exist give this error instead of a 404), I get the exact same message (the path is always '/'). Any ideas?
Server Error in '/' Application. Failed to map the path '/'. Description: An unhandled exception occurred during the execution of the current web request.

UPDATE: I went back to the site a few minutes after posting this--made no changes to code or configuration--and the error went away. I'm really baffled, but it is no longer a problem. Not sure what should be done with this question.
I had the same issue (MVC 4) under IIS 7. It turned out that the App Pool identity didn't have the correct authorization to the site's path.
I also have same issue. In my case working on InstalledSheild / InstalledAware, to make setup of web service. After setup run the above error comes, while resolve issue when check, found that IIs default website path remove after setup run.
So I just add path as below step.
This line (top of the stack trace) is telling you there is something wrong which the hosting configuration.
System.Web.HttpRuntime.HostingInit(HostingEnvironmentFlags hostingFlags, PolicyLevel policyLevel, Exception appDomainCreationException) +336
How is your server set up? Have you checked the config files?
I'd search through them specifically for any settings or attributes which have the single value "/".
I Think this is because of IIS is unable to find the root folder. i.e wwwroot. Restarting the IIS wont be helpful in some scenarios. if the root path has changed, you should bring it back to %SystemDrive%\inetpub\wwwroot
by right clicking sites node in IIS and changing physical path to the above one.
and make sure that your application pool is asp.net v4.0 and running in integrated mode
i have tried following solution and it had work for me C:\Program Files\Microsoft Visual Studio 10.0\Common7\IDE\devenv.exe right click on Devenv.exe in Compablity tab --> Privilage Level --> click on Run this Program as an Adminstrator If as for the Admin Password Provide it
if it is already selected deselect it and again select it -->Apply-->OK
restart the VS application and Publish your website again
I experienced this after updating to Windows 10 Fall Creators edition version 1709. None of the solutions above worked for me. I was able to fix the error this way:
If IIS Manager is not available under Administrative Tools, you can enable it this way:
I had this issue with a specific application and not the entire IIS site. In my case, access to the application directory was not the problem. Instead, I needed to give the application pool a recycle.
I think this was related to how the application was deployed and the IIS settings were set (done via scripts and a deployment agent).
